Abstract: 1303258 Fluid-pressure servomotor systems LINDE AG 5 Nov 1970 [6 Nov 1969] 52640/70 Heading G3P The output member 21 of a servo system is connected by springs 23,123 with fluid pressure responsive control valves 11. 111. When the member 21 is in a central position, the valves 11. 111 connect spaces 11, 118 at opposite ends of the piston to a motive fluid supply pump 1 which also supplies a pair of valves 5. 6. If, for example, the valve 5 is operated to increase the pressure in a space 9, valve 11 is moved to the right to connect space 18 through a line 20 to a pump 2 so that the member 21 is moved to the right by the pressure in the space 118 to compress the spring 23 and move the valve 11 back towards its original position until the space 18 is disconnected from both the line 20 and the pump 1. Actuation of the valve 6 operates valve 111 and causes movement of the member 21 to the left. Pins 25, 125 connecting the valves 11, 111 with spring abutments 24, 124 are provided with a collar 26 to balance the effect of the fluid-pressure in the spaces 18, 118. In a modified construction, the fluid-pressure in these spaces is used to bias the member 21 towards its central position. A bush 32, Fig. 2, provides a greater effective area subjected to pressure when the member 21 moves to the left while an extension (31) provides a smaller effective area than the opposite end of the member 21 when the latter moves to the right. A space (34) connected by a line (39) to the sump has a face (37) engaged by the bush when the member 21 is central.

Abstract: 1,242,007. Testing vehicle brakes electrically. SUN ELECTRIC CORP. Nov.14, 1968 [Nov.14, 1967], No.54064/68. Heading G1N. The brakes of a vehicle are tested by locating the front (or rear) wheels on a roller stand, driving the left and right hand roller pairs by independent electric motors and measuring the speed of rotation of the rollers when the brakes are applied, the differential of this signal giving the braking force and the integral of this signal giving the braking distance. Each roller is coupled to a photo-electric tachogenerator whose output frequency is converted at 15a-15d Fig. 3 to a corresponding voltage speed signal U v . The signals from the rollers of each pair are added at 18a, 18b and may be fed to speed indicators. When the brakes are applied to reduce the speed, the differentials of the speed are obtained at 19a, 19b, the resulting signals U k1 , U kr  representing the power developed by the individual wheels. The power supplied by the driving motors 5, 6 is measured by current transformers 20a, 20b, phase-sensitive rectifers 21a, 21b and networks 22a, 22b where the motor losses are subtracted, the resultant signals being added at 23a, 23b to the wheel power signals to obtain at 26a, 26b indications of the brake power at each wheel. Each signal may be multiplied by a factor representing the mass of the wheel and roller system, to determine the decelerating effect of the brakes. The maximum value of the signals is stored on capacitors 28a, 28b and indicated at 29a, 29b. An overload safety device switches off the motors 5, 6 when the brake power signals at 26a, 26b exceed a predetermined value. The distance travelled after braking and switching off motors 5, 6, as measured by integrating the speed signals, is inversely proportional to the average brake power.
